The general problems of particle motion in the vicinity of a flat, non-deforming fluid interface is studied. The approximate singularity method used by previous workers in this research group has been generalized to consider the motion of a sphere in any linear velocity field compatible with the existence of the undisturbed flat interface, and the motion of slender rod-like particles which undergo an arbitrary translation or rotation in either a quiescent fluid or in a linear flow. The theory yields the hydrodynamic mobility tensors which are necessary to describe Brownian movement near a phase boundary, as well as general trajectory equations for sedimenting particles near a fluid interface with an arbitrary viscosity ratio. These approximate solution results are in good agreement with both exact-solutions where they are available and experimental data for motion of a sphere near a rigid plane wall. Among the most interesting results for motion of slender bodies is the generalization of Jeffery orbit equations for linear simple shear flow.

Fluid flow through flexible tubes is of interest due to its dynamic similarity to that of fluid flow in veins, arteries, bronchial air ways, urethra, vocal codes peristaltic tubes, and flexible micro-fluidic devices. Similar behavior can be observed in diagnostic and therapeutic devices pressurized cuffs, prophylaxis, intra-aortic balloon counterpulsation, prosthetic heart devices, vein cannulation and prosthetic vocal codes. Due to the flexible material that constitutes the tube a state of total collapse is highly likely when the tube is subjected to excessive external forces. Thus, muscle contraction and expansion and external forces that act upon the vessel wall all serve to deform the flexible tube thereby affecting the fluid flow area and fluid flow behavior. It is reasonable to conclude that fluid flow within a flexible vessel is a function of the fluid properties, material prosperities of the flexible structures and any external forces. Furthermore within the flexible tube, the presence of attached internal structures can impose further limitations on the fluid flow. Such systems can be found in vein and valves, heart valves and also in nebulizers.
